Communications Settings

6-1-1

Introduction

G3PW Constant-current Models can perform serial communications with EJ1
Modular Temperature Controllers or SYSMAC CS/CJ/CP-series PLCs. The
CompoWay/F communications protocol is used. CompoWay/F is a generic
serial communications protocol from OMRON. An RS-485 interface is used at
the G3PW. 

Communications 
Specifications

Note

CompoWay/F

CompoWay/F is OMRON's standard communications format for general
serial communications. 
It uses commands compliant with the well-established FINS used exten-
sively with OMRON Programmable Controllers together with a consistent
frame format to facilitate communications between more than one compo-
nent and between personal computers and components. 

FINS (Factory Interface Network Service)

The FINS protocol provides message communications between control-
lers in OMRON FA networks.
